Description

Technical Field

[0001] The present invention belongs to the field of vibration control technology, and more specifically, relates to a flywheel inertia vibration reduction device and method with intelligent adjustable damping. Background Art

[0002] With the rapid development of modern industry, in application scenarios such as super-high buildings and long-span bridge structures, vibration reduction devices are usually used to dissipate energy and reduce vibration in order to avoid structural safety hazards and economic losses caused by large vibrations. Although traditional vibration reduction methods such as the use of spring shock absorbers or hydraulic dampers can alleviate vibrations to a certain extent, they often lack flexibility and intelligent adjustment capabilities. Traditional vibration reduction technologies, such as the use of elastic materials such as springs and rubber, can absorb and disperse vibration energy to a certain extent, but they often seem powerless when dealing with vibrations of different frequencies. What's more serious is that after long-term use, these elastic materials will experience problems such as aging and fatigue, resulting in a sharp decline in vibration reduction performance or even complete failure.

[0003] In the field of vibration control, flywheel inertia vibration damping devices are a common device used to reduce the vibration and noise of the system. The working principle of flywheel inertia vibration damping devices is mainly to offset vibration by increasing the inertia of the system. When the mechanical system is vibrated by external excitation, the flywheel inertia vibration damping device balances the vibration through the inertial force generated by the mass of its rotating part. At the same time, the damper inside the device is used to consume vibration energy, thereby reducing the amplitude and duration of vibration. However, traditional flywheel inertia vibration damping devices usually have fixed inertia and damping characteristics. When faced with complex and changing working environments, they cannot be adjusted according to actual work needs, which limits their applicability in different application scenarios.

The flywheel assembly can store energy and release energy when needed. By adjusting the inertia mass and damping characteristics of the intelligent variable resistance module, the problem that the traditional flywheel assembly inertia vibration reduction device usually has fixed inertia mass and damping characteristics is solved. The intelligent variable resistance module adopts intelligent control technology and sensor technology, and can monitor the vibration state and parameter changes of the mechanical system in real time, and can effectively improve the vibration control performance of the system.

A flywheel inertia vibration reduction method with intelligent adjustable damping, characterized in that: The invention is implemented by using a flywheel inertia vibration reduction device with intelligent adjustable damping as claimed in any one of claims 1 to 9, comprising: S100: Installing the vibration reduction device on the structure that needs vibration reduction, ensuring that the left ear plate (1) and the right ear plate (15) of the connection module are connected to the relatively vibrating part of the structure; S200: When the structure vibrates, the vibration is transmitted to the hydraulic system module through the left ear plate (1) and the right ear plate (15), driving the piston rod (2) and the piston (6) to perform reciprocating linear motion. The movement of the piston (6) causes the damper medium (16) to enter the hydraulic motor (11) through a series of pipelines; S300: The hydraulic motor (11) converts pressure energy into mechanical energy, drives the flywheel assembly (12) in the conversion module to rotate and store energy, and when needed, the flywheel assembly (12) releases the stored energy and converts it into pressure energy through the hydraulic motor (11) to reduce or suppress vibration; S400: The hydraulic motor (11) drives the flywheel assembly (12) to rotate, driving the motor (13) to work synchronously. Through the operation of the motor (13), the intelligent variable resistance module (14) can monitor the vibration state and parameter changes of the structure and collect vibration data of the structure; S500: Calculate the required damping force based on the collected data, and adjust the inertia and damping characteristics of the device through the intelligent variable resistance module (14) according to the calculated damping force to adapt to the current vibration conditions, continuously monitor the vibration state of the structure, and adjust the damping characteristics in real time as needed to ensure the best vibration reduction effect.
